Answer:
The equation that will determine the cost of two folders is; 3x = 2× $2.91
and the cost of the 2 folders is $1.94
Step-by-step explanation:
To solve this problem, we will follow the steps below;
Using proportion;
Let x be the cost of 2 folders
3 folders = $2.91
2 folders = x
Cross-multiply
3x = 2× $2.91
The equation that will determine the cost of two folders is
3x = 2× $2.91
We can go ahead and solve
3x = $5.82
Divide both-side of the equation by 3
= 
x = $ 1.94
The cost of 2 folders is $1.94

Answer:
-2
Step-by-step explanation:
slope: (y² - y¹) / (x² - x¹)
(-1 - 1) / (1 - 0) = -2 / 1 = -2
y = -2x + b
plug in an (x, y) value to find b
1 = -2(0) + b
1 = -2 + b
b = 3
y = -2x + 3
rate of change is -2
Answer:
289/4
Step-by-step explanation:
x² + 17x + 12 = 0
x² + 17x = -12
Take half of the second coefficient, square it, then add the result to both sides.
(17/2)² = 289/4
x² + 17x + 289/4 = -12 + 289/4
(x + 17/2)² = 241/4

8 lemons
</span><u>Explanation</u><span>
If 2 lemons cost 15 cents, then 1 lemon would cost;
15÷2=7.5 cents.
To get the number of lemons that can be bought we you divide 60 by the cost on one lemon.
That is;
60÷7.5=8 lemons.
